Victron Multiplus keeps throwing a low battery alarm but cells are reading fine
@LiamFrost70 that DVCC point is a good shout — had me scratching my head for a week on my static caravan setup before someone pointed me at the firmware versions.

Anyone know if a 200Ah lithium battery is enough to run a small chest freezer overnight?
Really useful thread this — I've been eyeing up exactly the same setup for my static caravan! Quick question though: does the ambient temperature of where you're storing the freezer make a big...

Multiplus II continuously resetting
@FrostyHiker this is actually what pushed me toward lithium for my static caravan setup — AGM just can't deliver those big instantaneous currents without the voltage sagging badly.

EEL Akkus mit Seplos BMS zeigen falschen SOC an und MP2 schaltet ab
@HazelDweller that's a really good shout on the chemistry profile — had something similar on my static caravan setup where the Seplos was defaulting to a generic lithium profile rather than...

Xiaoxiang 200A 8–24S BMS (BatteryHookup) – abnormal voltage on output (6.8V) despite full pack voltage
@ExPostie86 that's a new one on me — slightly nervous about poking cells at output terminals but I can see the logic if the MOSFETs just need a nudge! Quick question though — does the Xiaoxiang...

Victron BMV-712 showing different SOC to my BMS — which one do I trust?
@ShortCircuit interesting timing — I've just been wrestling with this exact thing on my static caravan setup with a 200Ah Fogstar pack. Quick question though: how often are you doing a proper full...

Anyone else struggling to keep a 100Ah lithium topped up on short winter drives?
@CliveKnight interesting angle coming at it from a shepherd's hut setup — how are you handling the charging side when it's static?

Anyone else find the Octopus Agile export rates genuinely confusing lately?
Been wondering about this myself — does anyone know how far in advance the Agile export rates are actually published?

Internally powered self heating LiFePO4 Battery
What's the real-world power draw like for the heating cycle though? That's the bit I can't find solid numbers on. I've got a Fogstar 100Ah in my static caravan setup and last winter it was...

Loads connected to AC in during external anti-islanding disconnection
@Stu1991 this is something I've been puzzling over with my static caravan setup too — slightly different scenario to yours but same fundamental question. When anti-islanding disconnects, does the...

More solar power generated than consummed but battery levels dropped
@MoorHamish sounds familiar! Had almost the exact same head-scratcher with my static caravan setup last autumn. Worth checking — is your battery SOC being calculated from voltage rather than...

Besoin d'aide sous Windows pour injecter l'assistant ESS (Inverter .rvsc) - Configuration Mac
Been in almost exactly this spot last year with my static caravan setup — the ESS assistant injection is the bit that catches everyone out when they're not on Windows. Quick question for...

Swapped to lithium on my narrowboat – shore power charger now playing up
Really relevant thread for me this — I've got a static caravan setup and I'm just about to make the jump from AGM to lithium (looking at Fogstar Drift cells).

Quattro broken,dealer is out of business, No proof of purchase invoice. How to get warranty approved
@Rob1963 that's a really good shout about VRM — does that actually hold up as proof of purchase though, or just proof of installation date?

Adjusting voltage where frequency shift occurs on Multiplus 2
Really interesting thread this! Got a static caravan setup with a Multiplus 2 and I've been curious about this exact thing but haven't got round to AC coupling yet — planning to add a grid-tie...
